PDC's diaphragm helium compressors are the preferred choice when contamination-free, leak-tight helium compression is required. PDC diaphragm helium compressors are designed to afford you high quality, high reliability, low maintenance and extended service intervals. PDC users have reported up to 40,000 hours without any parts replacement needed except for oil changes. Based upon our extensive experience in compressor technology, and our state-of-the-art engineering and manufacturing capabilities, we work with our customers to provide the optimum solution to satisfy their helium gas compression needs. PDC provides both standard and custom designed helium compressors with a comprehensive assortment of options. We furnish a wide range of equipment from basic units to turnkey, skid-mounted and computer controlled systems. Our helium compressors range in size from 3 hp to 200 hp (3 to 150 Kw), discharge pressures vary from 50 psig to over 6000 psig (3 barg to over 413 barg).
PDC diaphragm helium compressor includes: State-of-the-art manufacturing - All critical components are manufactured at PDC, assuring the highest levels of quality control. This also allows us the flexibility to accommodate tight delivery schedules. Enhanced diaphragm life - All aspects of our diaphragm helium compressor design are intended to enhance component life, improve operation and reduce and simplify maintenance. Diaphragm cavity contours, which control stress in the diaphragms, are precisely machined to provide uniform stress distribution. These cavity contours are computer engineered utilizing Finite Element Analysis techniques. Diaphragm surfaces are specially treated to extend fatigue life. Automatic unloading system - PDC's helium compressor is automatically re-primed at start-up. Incorrect priming will cause cavitation inside the compressor and could lead to damage ofthe heads, head bolts, diaphragms, O-rings, or the process and hydraulic systems. Automatic unloading eliminates the need for technicians presence to re-prime the compressor. Hydraulic oil system -The hydraulic system is designed to assure uniform diaphragm deflection, prevent knocks, vibration, cavitation and yield smooth, quiet compressor operation. Unique oil distribution techniques are employed to eliminate pressure differentials and gradients. The system utilizes an automatic priming pump, positive displacement high-pressure injection pump and oil relief valve with bypass valve for smooth, easy starting. High Product purity -The triple diaphragm set ensures that the process gas is isolated from the hydraulic oil. Environmentally safe -PDC uses static seals and there is no migration of helium gas to the crankcase. The crankcase does not require purging or venting, so there is no leakage of process gas to the atmosphere. Corrosion resistant wetted materials -All process contacting parts are made from stainless steel and high strength polymers. This helps to prevent premature failure of the diaphragms and reduces the cost of spares needed, reduces maintenance frequency and reduces down-time. Safety interlocks -Features include shutdowns for low suction, high discharge, low oil, low water coolant and diaphragm or O-ring failure. Audible and visual enunciators can be supplied for an added level of protection. The helium compressor will be completely instrumented for automatic operation. Lower Energy Costs- Duplex and two-stage diaphragm helium compressors are horizontally opposed designs which reduce horsepower requirements and energy costs. International standards compliance - PDC diaphragm helium compressors can be designed and certified to comply with European, American, Canadian, Japanese and other international directives including the National Electrical Code (NEC), Canadian Standards Association (CSA), High Pressure Gas Safety Institute of Japan (KHK), and the European Union's Pressure Equipment Directive (PED) and ATEX directive for machinery. Typical applications include but are not limited to:- * Helium re-fueling stations for vehicles, buses and material handling * Filling & off-loading helium gas from tube trailers * Cylinder filling compressor with helium gas & bulk storage tanks * Blending, recycling & mixing of helium gas * Helium feedstock for chemical, petrochemical & pharmaceutical industries * Helium for deep sea diving sector * Helium gas for welding and cutting * Helium gas for the production of silicon wafers * Flat glass production * Helium for aerospace applications * High pressure boosting & storage of helium gas from gas generation systems
